One day I suddenly found that my GPU temp. is 95 C. I am surprised. After some checking I have found rundll32.exe uses 99 CPU. If I stopped it, temp goes down to 25 C.

When I open Task Manager and open file location of rundll32.exe program, It's shows:

C:\Users\Prosenjit\AppData\Local\Temp\7C11.tmp\rundll32.exe

After Temp folder next folder location change in every restart. when I end the process of this, screen black and after few second it's shows Display driver stopped working and recover successfully.


Please help me.
Thanks in advance.
 
That's weird.
rundll32.exe is usually in system32 folder. It is probably a virus. Try clearing your cache and temp files and see if the problem persists
 
I have original KAV 2012 fully updated. Scan so many times, Delete cache and temp everytime. But after restart it start automatically.
 
you will have to use the combination of process explorer and autoruns. usually viruses addes the startup entres immediately after you've deleted them. first you figure out the startup entries using process explorer's image info and the autoruns tools. then kill parent process or the service which is spawning the rundll. then kill the rundll and then after that remove the startup entries. reboot the machine. then check the running processes and startup entries again.
 
Thanks to all of you...

I have installed Quick Heal Total security 2013 Trial and scan whole Computer HDD. Now the problem is solved with some data deleting.. Anyway it's good.
